Answer #1

Hearing : The sound entring the ear takes the following path,

External Audiotory Canal ----> Tympanic membrane ---> enters middle ear -----> Malleus ----> Incus ------> Stapes -----> oval window ---> Inner ear --------> Chochlea (Scala Vestibuli) -----> Organ of Corti ------> Auditory division of vestibulocochlear nereve ( CN - VIII) ------> Cochlear nucleus in the medulla ----> Inferio Colleculi ( Center for audiotory reflex) -----> Medial Geniculate Body ------> in Brain, auditory cortex (Area 41) In the superior portion of the temporal lobe in the sylvian fissure.

How does the fly control differentiation of epithelial cells to nerve cells so that nerve cells are not over-produced? Group of answer choices The Notch receptor is present on epithelial cells. When an epithelial cell develops into a nerve cell, it expresses Delta on its outer cytoplasmic membrane instead of Notch. Delta is a ligand for Notch. When a Delta-bearing nerve cell touches a Notch-bearing epithelial cell, it inhibits the epithelial cell from differentiating into a nerve cell. As the...
